On our typical Producer Completions in the White Rose field we run a 6-5/8" x 5.5" tapered lower Sand Face Completion (1500-2500 m SAS & ICDs and Swell Packers) on a Liner Hanger, install a Fluid Loss device on a separate trip and than run an upper completion (Packer, TRSV, Gas Lift , Chemical Inection) after running the Horizontal XMT.
All wells are subsea (~120m water depth)
On the installations planned for the this year the trajectory of the wells is getting very challenging and from T&D modeling getting our Lower Screen Completion to bottom will be challenging or impossible with conventional 1-trip/sliding to bottom. The modeling is showing severe buckling in the SAS.
Our options we are investigating are:
Ability to install SAS/ICD completion with while rotating Screens/Swell Packers: Our SAS do have a Hydril connection on them but we have never required to rotate to install the lower screens, until now. Is this routinely done? Any learnings anyone can share?
Use of a Swivel above the Liner Hanger. Experience/Learnings running Swivels for similar applications?
Running the SAS/ICDs in stages using a drop off tool: Experience/Learnings dropping Screens off in segments?
Any feedback anyone can offer would be much appreciated.
